The model-turned-entrepreneur's signature lingerie line, Elle Macpherson Intimates (far left), is a best-selling success, stocked at Bloomindales, Saks Fifth Avenue, and Neiman Marcus. She's also launched a skincare collection, called (of course) "The Body", and recently became the host of Britain's Next Top Model. And, in March, she made a triumphant return to the runway, closing Louis Vuitton's buzzed-about Fall 2010 show (right).

Canadian-born Evangelista got her start when she was spotted by a talent agent at a Miss Teen Niagara pageant in 1978. Ten years later, she lost a number of major runway bookings when she suddenly swapped her then-shoulder-length hair for a boyish, close-cropped style, but her ever-changing 'do eventually became her trademark. A face of Revlon, Donna Karan, and Versace, she famously told a reporter in 1990 that she and her supermodel colleagues "don't get out of bed for less than $10,000 a day."

Discovered at 15 while window-shopping in London's Covent Garden, Campbell quickly went from being an in-demand catwalk star (at left, she's seen walking runways for YSL and Versace) to posing for numerous magazine covers, many of which had never before featured a black model. She represented Nars, Ralph Lauren, and Prada, appeared in music videos for Madonna, George Michael, and Michael Jackson, and dated Mike Tyson, Robert DeNiro, and Eric Clapton.

Although plagued by personal scandals, Campbell is still a fashion-world star. Next month, Dolce and Gabbana will celebrate "the 25th anniversary of her career" with a party and limited-edition T-shirt; proceeds will benefit her charity, Fashion For Relief, which also held a fashion show to benefit Haiti earlier this year (above).
